Replacing an AP-TMZ1600-0 sensor
connected to a VMA Controller
To replace an AP-TMZ1600-0 sensor connected to a
VMA controller, complete the following instructions.
Note: The AP-TMZ1600-0 sensor is not
supported for use with the VMA18 controller
and must be replaced with an NS Series
Network Sensor. Refer to the NS Series Network
Sensors Product Bulletin (LIT-12011574) for a
complete list of available NS Series Network
Sensors.
1. Remove the AP-TMZ1600-0 sensor and
disconnect the 8-pin male jack from the back of
the sensor.
2. Plug the 8-pin male jack from the VMA
controller into the 8-pin female socket on the
single-socket adapter (Figure 10) included with
the VMA18 controller.
3. Plug the 6-pin male jack on the single socket
adapter into the modular jack connection on
the back of the NS Series Network Sensor.
4. Mount the NS Series Network Sensor in the
same location the AP-TMZ1600-0 Sensor was
previously mounted, concealing the adapter
assembly in the existing wall opening behind
the sensor. Refer to the installation instructions
for the applicable NS Series Sensor model.
5. Plug the BTCVT into the 6-pin socket on the NS
Series Network Sensor.
Note: When using an NS Series Network
Sensor with screw terminal block terminations,
see the wiring diagram in the installation
instructions for the applicable NS Series Sensor
model.

Receiver connected to a VMA Controller
To replace a TE-7710-0 Series Wireless Transmitter
and TE-7720-0 Wireless Receiver connected to a VMA
controller, or to convert the wired sensors used
with the VMA18 controller to wireless, complete the
following instructions.
Note: The TE-7710-0 Series Wireless
Transmitter and TE-7720-0 Wireless Receiver
must both be replaced with a WRZ Series
Wireless Sensor and a WRZ7860-0 Series

2. Plug one end of the 6-foot interface cable into
the VMA18 socket labeled TSTAT.
3. Plug the other end of the 6-foot interface cable
into the 8-pin female socket of the single-socket
adapter.
4. Plug the male end of the single-socket adapter
directly into the BTCVT.
5. Complete commissioning of the VMA18
controller and disconnect the BTCVT.
Note: Sensor point information such as
temperature, setpoint, and occupancy is
not available during commissioning.
6. Install the WRZ Series Wireless Sensor and
a WRZ7860-0 Series One-to-One Receiver in
the same locations as the previous sensor
and receiver. Refer to the WRZ Series Wireless
Room Sensors Installation Instructions (Part No.
24-10332-2) and the WRZ-7860-0 Installation
Instructions (Part No. 24-10563-47) .
7. Plug the 6-pin male jack on the adapter into the
